Description

Technical Field

[0001] The utility model relates to the technical field of heating without burning, and in particular to a double-disc type sensor unwinding device. Background Art

[0002] Heat-not-burn cigarettes are a special tobacco product that has been developed in recent years. They are heated by electromagnetic heating or other heating methods to release the aroma components and other substances in tobacco products. Since tobacco products do not participate in combustion, they avoid the generation of a large number of harmful components due to high-temperature cracking at 900°C. While consumers gain satisfaction, they also reduce harm to the body and reduce environmental smoke pollution.

[0003] Most of the commonly used magnetic heating smoking segments are prepared by suction molding. The equipment for preparing smoking segments by suction molding is very common, the preparation process has been perfected, the production cost is low, the production speed is fast, and all types of tobacco can be produced. For example, the Chinese patent invention patent CN110558606A provides a tobacco suction molding device for a ZJ17 cigarette making machine, including: a wind chamber body, a suction belt wheel and a suction belt. A plurality of suction belt wheels are arranged in the wind chamber body, and the suction belt wheel is used to drive the mesh-shaped suction belt to operate continuously. When the process suction air passes through the wind chamber body, the mesh on the suction belt forms a negative pressure and absorbs the tobacco into the mesh to form a tobacco bundle. The meshing surface of the suction belt wheel is surrounded by an arc groove, so that the suction belt meshes along the arc groove when the suction belt wheel is driven to operate, so that the tobacco bundle absorbed by the suction belt forms an arc structure. The above invention can reduce the production cost of cigarettes and improve the quality of tobacco processing.

[0004] However, the magnetically heated smoking segment formed by the suction wire does not contain a sensor, and a sensor needs to be inserted into the magnetically heated smoking segment prepared after the suction wire is formed, or a specific cigarette lighter with a sensor pin is required to electromagnetically heat the smoking segment.

[0005] Although there is a design of implanting a sensor in the smoke-generating section, the sensor steel wire needs to be transmitted synchronously with the suction wire rope. The suction wire rope is generally very long, but the sensor needs to be unwound by a sensor unwinding disk. The length of a roll of sensor is much shorter than the length of the suction wire rope, so multiple rolls of sensor need to be unwound alternately. The mass of the sensor roll is large, and the unwinding control and replacement are difficult. In addition, the two ends of the sensor need to be welded when the two rolls of sensor are unwound alternately. The unwinding and alternating stability of the steel roll is poor, resulting in low efficiency of the entire sensor unwinding.

[0006] Therefore, in order to solve the above problems, it is necessary for us to design a reasonable double-disc sensor unwinding device. Utility Model Content

[0030] In the utility model, the unwinding disk 1 is a large disk-shaped member, which can rotate around the central axis 11. A sensor shaft 2 is respectively arranged on both sides of the central axis 11 of the unwinding disk 1. A steel reel 3 can be arranged on each sensor shaft 2, and a sensor steel wire is arranged on the steel reel 3. The sensor on the steel reel 3 is driven by the feeding roller 4 to unwind the sensor.

[0031] Of course, the two sensor shafts 2 are symmetrically arranged on both sides of the central shaft 11. The unwinding reel 1 can be rotated by only driving the central shaft 11 to rotate, and when the unwinding reel 1 rotates 180 degrees, the positions of the two sensor shafts 2 can be swapped, so that the two steel reels 3 can be fed in rotation.

[0032] In the utility model, a magnetic damping member 5 is provided on the unwinding reel 1 , and a rotating shaft of the magnetic damping member 5 is connected to the sensor shaft 2 via a synchronous belt 51 .

[0033] Here, the magnetic damping member 5 and the central axis 11 are both arranged on a side of the unwinding reel 1 away from the steel reel 3 .

[0034] It should be noted that the central axis 11 is only arranged on the back of the unwinding disk 1; the sensor shaft 2 passes through the unwinding disk 1, and the unwinding disk 1 is provided with a bearing for connecting the sensor shaft 2, so that a part of the sensor shaft 2 is located on the front of the unwinding disk 1, and a part is located on the back of the unwinding disk 1; a steel coil 3 is provided on the sensor shaft 2 located on the front of the unwinding disk 1, so that the sensor is only unwound on the front of the unwinding disk 1; a magnetic damper 5 is connected to the sensor shaft 2 located on the back of the unwinding disk 1, and the rotation speed of the sensor shaft 2 is controlled by the magnetic damper 5 to avoid over-speed unwinding of the sensor; the sensor shaft 2 can also be braked by the magnetic damper 5 when the two steel coils are rotated.

[0035] The utility model discloses a double-disc sensor unwinding device with a simple structure. Two groups of steel coils are symmetrically arranged on the unwinding disc, one of which is in use and the other is used as a spare disc. The two steel coils are quickly rotated and unwound by rotating the unwinding disc, and a new spare steel coil is installed at the spare disc. The rotation of the unwinding disc ensures that the fracture directions of the sensor splicing parts are consistent during splicing. The sensor disc adopts hysteresis damping for braking, so that the whole unwinding process and the alternating process have high stability and the sensor unwinding efficiency is high.

[0036] Embodiment 2, as Figures 1 to 3 The figure is only one of the embodiments of the present invention. On the basis of the first embodiment, in a double-disc sensor unwinding device of the present invention, a transition roller group 6 is arranged on the unwinding disk 1, and the transition roller group 6 includes a first roller 61, a second roller 62 and a third roller 63.

[0037] In one embodiment of the utility model, a pressure sensor is provided on the second roller 62, and the pressure sensor is a ceramic piezoelectric sensor, and the pressure sensor is electrically connected to the magnetic damping element 5. That is, when the second roller 62 is close to the ceramic piezoelectric sensor, it means that the transmission pressure of the sensor is too large. At this time, the magnetic damping element 5 adjusts the rotation speed of the sensor shaft 2, thereby adjusting the unwinding speed of the sensor.

[0038] Of course, a rocker arm is provided at the second roller 62, one end of which is fixed, and the other end of which is connected to the second roller 62. The rocker arm has elastic force to swing back to the center. When the transmission speed of the sensing body is too fast, the end of the rocker arm close to the second roller 62 will approach the pressure sensor under pressure. At this time, the magnetic damper adjusts the speed, and then the rocker arm returns to the center and moves away from the pressure sensor under the elastic force.

[0039] In an embodiment of the present invention, the number of the transition roller groups 6 is two, and the two transition roller groups 6 are symmetrically arranged on both sides of the central axis 11; one steel coil corresponds to one transition roller group 6.

[0041] In one embodiment of the present utility model, the unwinding disc 1 is provided with a connecting bearing for connecting with the sensor shaft 2 .

[0042] Finally, the unwinding drum 1 is an integrally formed part.

[0043] The utility model discloses a double-disc sensor unwinding device with a simple structure. Two groups of steel coils are symmetrically arranged on the unwinding disc, one of which is in use and the other is used as a spare disc. The two steel coils are quickly rotated and unwound by rotating the unwinding disc, and a new spare steel coil is installed at the spare disc.
